Purpose-built workstation

This desktop is assembled for engineers and researchers who need a 12-core AMD Ryzen 9 9900X paired with 32GB DDR5 memory. The system targets SolidWorks modelling and AI learning workloads that benefit from high single-thread frequency and professional GPU drivers. It ships with Windows 11 Pro 64-bit and liquid cooling for sustained operation.

32 GB RTX PRO 4500 GPU

The Nvidia RTX PRO 4500 Blackwell provides 32GB of video memory on a PCI Express x16 link. That frame-buffer capacity is the single specification that determines whether large assemblies, simulation datasets or training batches fit entirely on the card. Without it, workflows would spill to system memory and lose interactive performance.

Liquid-cooled 12-core CPU under load

A 240 mm quiet-edition AIO keeps the Ryzen 9 9900X at its 4.4 GHz base clock during extended renders or simulations. The 850 W 80 PLUS Bronze power supply delivers stable current to both the CPU and the 32 GB GPU without throttling. Thermal headroom remains consistent across multi-hour jobs rather than peaking only in short bursts.

Questions about this item

What does the Ryzen 9 9900X 4.4 GHz base clock deliver in a real workstation?

The 12-core processor runs at 4.4 GHz base and can boost to 5.20 GHz, giving strong single-thread speed for CAD and multi-thread throughput for AI learning workloads.

How does the PCI Express x16 link and the motherboard USB4 ports cap real-world throughput?

The GPU uses a PCI Express x16 slot, while the board provides two USB4 ports at 40 Gbps, three USB 10 Gbps ports and four USB 5 Gbps ports for peripheral bandwidth.

What clearance does the 240 mm liquid cooler and Corsair 4000D case need to fit on a desk?

The case measures 490 mm deep, 239 mm wide and 486 mm high; the 240 mm radiator mounts inside, so allow at least those external dimensions plus cable space.
